Control Architect's ribbon tabs are located at the top of the main window and provide all the features available within Control Architect in a categorized fashion. The ribbon tabs parts are:
The main tabs - They are always visible and are used for the most important actions
The tabs groups - When a tab is selected, it will display actions grouped by similar purpose
Contextual tabs - These tabs are only shown when needed. For example, the "SCM Language View" tab is only visible when an SCM Control Module is currently open in a Chart View.
